    Vacuum Forming

    Hey!
    I'm putting together a vacuum forming table with a buddy.
    We've got a 6.25HP Shop Vac, so that should suck pretty good!

    We're planning to make the one seen at StudioCreations, but I still need some practical input from you guys. Has anyone in here made one? If yes, please share your knowledge on what to do and what not to do, measurements and any other info like pics perhaps?

    Thanks boys & gals!

    Here's the table I just built...



    Most people use an oven but I wanted it to be all
    one unit. I used two large hotplates that I bought
    at Sears. They reach 400+ degrees. You need at least
    that much heat to soften up the plastic. Also, if you
    go with my kind of set-up...you need to make the heat
    canopy completely enclosed. If you let any heat escape
    the plastic won't get hot enough.

    Hope this helps.

    Very sexy!

    What is the size of plastic you can form?
    And what do you usually use to make the moulds?

    Thanks,
    Bobo

    My table can fit up to an 18 inch square
    plastic sheet. It can work on up to .100 gauge
    styrene or .085 to .090 ABS.

    I've used clay pots so far (still in the testing
    fases), but I plan on using lots of Ultracal 30
    based molds or carved wood.

    Cool, so what do you think is the best plastic to use? I'm planning to make some gauntlets and maybe other things.

    Do you have any pics of your test forms?

    The advice I have received tends to lean towards
    using HIPS (High Impact Poly Styrene) for most all
    Fett costume parts. Use ABS for things like Stormtrooper
    or Clonetrooper armor since it is more durable and
    less likely to crack and split due to lots of wear
    and stress on joints & such.

    May I suggest Hydra-Stone... just that much stronger and little to no price difference

    Hrm, so Hydra-Stone is good for vac moulds?

    Hydra-stone...I think I'll give it a try.
    The Ultracal molds I've been toying with
    have a tendancy to crumble a little bit
    every time I use it.

    Do you have a name of a distributer of that
    Hydra-stone stuff?

    I've never used Hydra-Stone (will have to try that), but we found that Fix-It-All works well, too. Although it takes a few days to dry good enough to sand, it dries hard as concrete and costs about $6 for a 25 lb bag. Get it at Home Depot, used for repairing holes in walls and such, green and yellow bag.
